- of and means for ini'iunting pneumatic tires on the Wheels of such vehicles, the ob ect being tofacilitate the mounting and dismounting of such time I The present invention relates particularly to wheels or that type which. are provided with circuinferentially divided rims one part of which is attached to the usual wooden folly or a plate carried thereon and the other or detac iable part 18 provided on its inner edge with looking cote res to enter 1 corresponding recesses in the attachedpart or in the plate carried on said folly radially F arranged bolts orspring-controlled studs being provided. for retaining the parts in engagernent,'and comprises an rnproved conv struction of rimiand locking device in combination with an auxiliary rim or band for carrying the complete tire-partially inllated or deflateih when not in position on the wheel.

In the accompanying drawing which illustrates thisinvcntion, Figure 1 is a broken view 111 longitudinal section oi a wheel constructed according to the present invention,

' Fig. 2 is a broken view in pl an of the divided rim, Fig. 3 is a viewin transverse section of the fell and tire and i i x i is-a broken .view in side elevation of the auxiliary rim or hand.

Throughout the views similar parts are inarkedwith like letters of relercnce.

' The rim of the wheel having iii-curved. edges ada ted to receivethe usual thickened edges 3; 0 'o the elem-her type of tire to is formed in two parts an by dividing it in a circumferential direction. The one part a carrying one of the iii-curved ed gee o is :xer mane'ntly attached to the'felly of the wheel 1 and-the other part a carrying the other in-curved edge a is adapted to be easily rernoved from and locked to the felly oi the wheel '3 by a suitable locking device or de vices to be presei'itly described. The fixed part of the rim ct is preferably formed of a Bpecification oi Letters Patent.

width equal to is provided with an outwardly projecting centrally arranged circumferential rib a adapted to form an abutment for the inner edge of the removable part a: of the rim,

which latter is provided with one or more transversely arranged thiokeningpieces a corresponding in depth to cr -slightly less than the height of the circumferntial'rib a. These said pieces a are each preferably the width of the folly y and y formed with their edges at such an angle to 1 their surfaceas to form a' dovetail cross-section as shown, and are adapted to engage correspondingly formed recesses a, in the circumferential rib a. Y Theloeking devices consist of a plurality of radially arranged bolts 1) adapted to beoperated from the in ner side of the telly The bolt 1) passes through the felly y and a hole in the fixed art a of the rim; its-head N'engages ahole ormed in the removable part a, of the rim I and the thickening iece a carried thereby The belt bis contro led by means of acornpression spring b acting between the undersideofthe head b and a plate ythrough which the free end of the bolt asses-secured to the inner side ofthe fel y i p The shank of the bolt is providedwith flats or otherwise shaped and the hole in the plate 1 is correspondingly shaped in orderto prevent the bolt from turning around. A

lever b shaped at its one end so as to be easily operated by the fingers is'pivoted at b to the free end of the bolt. The free end b of this lever beyond its point of pivot b forinsits lulciuming point by engaging the plate y. The belt in its disengaged position is shown indot-and-dash lines on Fig. 3. The complete tire m deflated or part1 jinilated, is carried on an auxiliary rim or and 1 0 adapted to be slipped on the wheel over the fixed part a of the rim and before the removable part a is placed in position. This auxiliary rim 0 comprises a circumferentially expansible and contractible bandiprovided with a plurality of in-curved hooks or lips:

c on each of itsedges'. These hooks or lips c are adaptod to engage the thickened edges {13 on the tire eover'and hold them in osition and allowif desirablethe air to enot shown on the drawin s--to be partially inflated before the compete tire is put into position on the wheel. The hooks or lips 0 lie within the inecurved edges of a of the twopart'rim a a 'when the tire x is in position on the wheel... Itggfessential that the hooks or lips c shall be positioned or of such a number and form as to merely hold the thickened edges of the deflated or only partially inflated tire cover in place when oil the rim and allow the said thickened edges to properly engage the in-curved edges a a of the rim to take the Whole of the lateral strain exerted and *oining the ends c 0 together by means of a .ink c or plate hinged at 0 to each part of the, band, the arrangement being such that the ends 0 c of the band overla each otherin the contracted position (see ig. 4) for a distance e ual to or greater than the length of said lin or late and when the band is expanded (see ig. 1) with its tire cover 9; in position and the air tube inflated the said band 0. is incapable of contracting or only contracting within-limits defined by the play given to the hinge joints 0 A hooked szud c or the like is provided to facilitate pulling the band 0 into its contracted position. The rib a is cut away as shown in Figs. 1 and 2 in order to accommodate the linkc and stud c,

Security bolts d may sometimesbe employed, in which case they are formed with compound \\"e lge-sl'iaped heads (1 pro'ecting through the inner surface of the band 0 and adapted to engage correspondinglywedgeshaped transverse recesses a formed in the ireuml'erential rib a." of the iixed part a of the rim. 'l'ho lltltlS of said bolts areso formed that on m un ing the auxiliary rim or lmndc carrying the partially inflated tire, by sliding it literally over the iixed part a oi the wheel rim, the security bolts (1 will he radially moved, causing the plates d on their free ends to draw down the edges 1 of the tire. cover .1," and secure them to prevent the tire eover w creeping, and at the same time th hand 0 will he se( -.urely locked to the rim,

correspondingly shaped recesses formed In said rib, radially arranged spring-controlled bolts adapted to through said wedgeshaped thickening pieces and the fixed part and telly so as to hold and lock the parts of the riin together, and means'for readily operating said bolts and holding them open or in a disengaged position.

2. In a pneun'xatic tired Wheel for road vehicles having a two-part ciroumferentially divided rim with incurred edges, an auxiliary I'GllltlVtllJld hand adapted to be carried Within said rim, a hinged toggle joint'connecting the two ends of said band together so as to make it eireumferentially contractible and expansihle when not Within said rim, and a plurality of ineurved hooks or lips formed on the edges of said hand adapted to term porarily hold the usual thickened edges of the tire cover together when oil' the rim and in a deflated rendition yet allow said thielccued edges t properly and directly engage the usual ineurved edge of the rinmvhen the ;l ire is in position thereon, as set forth.
